Simple code inside index.js:

export default function js2string(InputFunction) {
    // {([^}]*)}
    const regex = /{([^]*)}/g;
    const exit = regex.exec(InputFunction.toString());
    return exit[1];
}

RegExp Patterns

/{([^]*)}/g – All In One Group
/{([^}]*)}/g – Multiply groups devided by (){} inside of main (){}

/g – is for global search.

Examples

example.js

// Example code to convert

const body = () => {
    console.log('Simple Example of source usage');
};



// Convert `const body` to string

function js2string(INPUT) {
    const regex = /{([^]*)}/g;
    const exit = regex.exec(INPUT.toString());

    console.log(`${exit}`);
}
js2string(body);

Returns

${exit}

{
    console.log('Simple Example of source usage');
},
    console.log('Simple Example of source usage');

${exit[1]}

    console.log('dataCollector() run SUCCESS');

// Example code to convert

    const getInside = () => {
        // so sweet.
    }
    const getMeOtherFunction = () => {
        // so sweet too...

Conclusion

You can modify that library to optimize some processes... any way it's just a simple code. It's all about mysterious...
